ok, this is what i have : pluged in my scaner before i started it and both o2's were reading 500 ish mv started the car they stayed the same till it started to get warm, the car went to closed loop and the lft went to 4mv at idle the right went to 120mv. rev the car to 2k and the right goes to 850ish around there and doesnt drop below 800 the left goes to 200 and dont go above. the car idles badley and celerates badlly, i am thinking that the lft bank is lean and cant figure out why. i dont want to damage it. when i go agound the block it stumbled badly. and also the lft long trim trim is higher then the rt. the rt is 145 and the lft is 160. do any of you guys have in idea were to start. i am going to swap the o2's and see what happens there. i cant hear any exhaust leaks but not to say there isnt somewere. Please help me out. i know that tune is good i have had a member here look at it and it is good. im trying to figure out what is going on with this thing.
